APPARATUS FOR ELIMINATING FOREIGN SUBSTANCES FROM WATER FOR OBTAINING CLEAR AND PURE ICE.

I SPECIFIGATION forming part of Letters Patent No. 317,366, dated May 5,1885.

Application filed February 5, 1885. (N0 model.)

T0 at whom it may concern.-

Be it known that I, FREDERICK JAEGER, a citizen of the United States, residing at Columbus, Franklin county, Ohio, have invented new and useful Improvements in Apparatus for Eliminating Foreign Substances from \Vater for Obtaining Clear and Pure Ice,of which the following is a specification.

This invention has for its object to provide novel means for obtaining clear and pure ice from streams which normally carry down more or less foreign matters, which, floating with the current and freezing in the ice, injure its quality, detract from its appearance, and may, if the stream isswollen, render it wholly unfit for use.

The object of my invention I accomplish in the manner and by the means hereinafter described and claimed, reference being made to the accompanying drawings, in which- Figure 1 is a view partly in elevation and partly in section. Fig. 2 is a horizontal section showing a modification. Fig. 3 is a projection of the screen shown in Fig. 2 detached. Fig. 4 is a view in elevation showing the screen illustrated in Fig. 3 attached to its supports. p

In the said drawings, the reference-numeral 1 indicates the bank of any stream of flowing water. To this bank is fastened, by any suitable means, abeam, 2, the end of which may be either set in the earth, as shown at 3,0r linked to a post, 4. To the beam, at suitable intervals, are attached stakes or bars 5, which are of such length as to reach to the bottom of the stream, or thereabout, and the entire structure is lowered into the water with the stakes I 5 in a vertical position by means of a rope, 6,

and any suitable tackle, 7, said rope being attached to a post or tree, 8, upon the bank.

In order to prevent the displacement of the structure by the force of the current, ropes 9 and 10 are used, which are anchored upon the bank at any suitable point above the beam 2.

In the outer end of the beam 2 are two or more stakes, 11, which pass through the said beam, their heads projecting above the same, and their length being greater than that of the stakes 5. These stakes are adjustable vertically, for the purpose of fastening the outer end of the beam by driving the stake or stakes into the bed of the stream. If desired, the stakes 5 may also be arranged within the beam, and may or may not be made adjustable. The length of the beam 2 is such that it will reach to the middle of the stream, or thereabout, and from the opposite bank a similar beam, 2, may be projected, which meets the end of the beam 2, the two conjointly spanning the stream. In a slow current the closely-arranged stakes will ordinarily arrest the impurities floating in the water; but when the current is swifter I employ the following modified apparatus: Along the top of each beam are placed bolts or strong nails 12, which engage with eyes or rings l3,connected with wire-netting, 14., which is of such width that it reaches substantially to the bed of the stream. This netting acts in conjunction with the stakes 5 and arrests the finer particles of matter. I prefer to attach the stakes to one side of the beam, and hang the netting from the other side,which faces upstream. Each section of the apparatus operates in the same manner, the wire-netting applied being attachable thereto, as circumstances may or may not render its use necessary. By this means I am able to obtain clear, pure water below the gate thus described, and this water, freezing, produces a clear, pure, and beautiful ice, which sells readily at a good price.

When in use, the beam must be put down at the proper time. When the water is forming ice and about to close up the stream, then the current is not so swift, and my invention can be easily applied with simple instructions. After the beam is down with stakes or iron bars or otherwise a little boat or skiff is used on each side of the stream below the beam or stakes. Sometimes one boat is sufficient to clear the river or stream for fifty to a hundred thousand tons of ice, and it may sometimes take three or four boats or skiffs, but hardly ever that many. These boats are moved up and down the stream along the shore, where the ice forms first, and the new ice is easily moved and kept going down the stream by spears and the boat cutting through the thick ly-formed ice along the shore. Where there are no trees along the shore, a horse or mule can be used to pull the boat or skiff to great advantage, or, still better, a little boat or tug used with steam, although this is more expensive. The beam and bars or stakes preventing any more ice floating downstream, the river is very soon cleared, and it will then, in nearly all cases, freeze clear and be a fine merchantable ice; but I do not stop there until I find the water is perfectly clear, little time being required for the stream to elearit self when it is frozen over above the beam and stakes, the time usually being from six to twenty-four hours. I have not known it to last longer than two days. An hour or two before the boats cease moving, which is done as soon as the water becomes clear, then I use the wire screens, or any kind of screen, as directed, to keep any floating ice or leaves or any substance from coming in that portion of the water which is intended for ice purposes. Another very important matter is, if there is a snow falling while using the boats they can be kept moving until it stops snowing, or the stream can be kept open if there is reason to believe, by weather indications, that there will soon be a fall of snow.

What I claim is- 1. The apparatus described for eliminating from a flowing stream the foreign impurities contained therein, said apparatus consisting In testimony whereof I affix my signature in' presence of two Witnesses.
